³ H-Bradykinin receptor binding

(i) Test Method

(a) Crude ileum membrane preparation

Male Hartly strain guinea pigs were sacrificed by decapitation. The ileum was removed and homogenized in buffer (50 mM trimethylaminoethanesulfonic acid (TES), 1 mM 1,10-phenanthroline pH 6.8). The homogenate was centrifuged (1000×g, 20 minutes) to remove tissue clumps and the supernatant was centrifuges (100,000×g, 60 minutes) to yield a pellet. The pellet was resuspended in buffer (50 mM TES, 1 mM 1,10-phenanthroline, 140 mg/l bacitracin, 1 mM dithiothreiol, 0.1% bovine serum albumin pH 6.8) and homogenized with a glass-teflon homogenizer to yield suspension which was referred to as crude membrane suspension. The obtained membrane suspension was stored at -80° C. until use.

(b) ³ H-Bradykinin binding to the membrane

The frozen crude membrane suspension was thawed. In binding assays, ³ H-Bradykinin (0.06 nM) and drug (1×10⁶ M) were incubated with 50 μl of the membrane suspension at room temperature for 60 minutes in a final volume of 250 μl. Separation of receptor-bound from free ³ H-Bradykinin is achieved by immediate filtration under vacuum and washed three times with 5 ml of ice-cold buffer (50 mM Tris-HCl pH 7.5). Non-specific binding was defined as binding in the presence of 0.1 μM Bradykinin. The radioactivity retained on rinsed filters was determined by a liquid-scintillation counter.

EXAMPLE 18

A mixture of phenylhydrazine (54 mg), N,N'-carbonyldiimidazole (81 mg) and 1,4-dioxane (3 ml) was stirred at ambient temperature for 3 days under nitrogen atmosphere.
